Local Environmental Conditions
Here, not far from here, a stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months. Located just around the area, this area has eucalypt and wattle growing together, with wattle's fine pollen especially potent during its short flowering window. Seasonal timing here generally tracks the wider region, give or take a week or so.
River oak along the water gets the season underway before other species, hitting its peak before most other trees flower, around July into September. As spring approaches, eucalypt and wattle in the nearby woodland become the dominant source, usually hitting its highest point sometime between mid-August and mid-September. Grass pollen builds through spring and peaks in November, before pollen counts gradually decline through January and February.

Does pollen in Williamtown come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Williamtown based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Williamtown, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
